Product Description

Product Description

E+H FDU90

In the realm of industrial measurement technology, the E+H FDU90 ultrasonic sensor by Endress+Hauser has emerged as a reliable and versatile solution for a wide range of applications. This sensor is designed to meet the demanding requirements of industries such as water and wastewater treatment, chemical processing, food and beverage, and many others. Its ability to provide accurate, non - contact measurements makes it an ideal choice for various level and flow measurement tasks.
For the measurement of solid materials, the FDU90 can handle powdery to coarse bulk materials. It can be installed in silos, on conveyor belts, or over stockpiles to determine the level of solids. In the mining industry, it can be used to measure the level of ores in storage bins, while in the food and beverage industry, it can measure the level of grains or powders in silos. The maximum measuring range for solids is 1.2 m (3.9 ft), and it can work well in environments where there may be dust or other particles in the air.

1. Technical Specifications

1.1 Measuring Principle
The FDU90 operates based on the ultrasonic time - of - flight principle. It emits ultrasonic pulses from the sensor head. These pulses travel through the air (or other medium) towards the surface of the material being measured. When the pulses hit the surface, they are reflected back to the sensor. The sensor then measures the time it takes for the pulse to travel to the surface and back. Since the speed of sound in the medium is known, the distance to the surface can be calculated using the formula: distance = (speed of sound × time - of - flight)/2. This principle allows for highly accurate and non - contact measurements.
1.2 Accuracy
The accuracy of the FDU90 is specified as ±2 mm + 0.17% of the measured distance. This high level of accuracy makes it suitable for applications where precise measurements are crucial. For example, in a chemical processing plant, accurate level measurement of reactants in a vessel can ensure the proper ratio of chemicals in a reaction, which is essential for product quality and process safety. The integrated temperature sensor plays a significant role in maintaining this accuracy. It compensates for changes in the speed of sound due to temperature variations in the medium, ensuring that the time - of - flight calculations remain accurate.
1.3 Process Temperature and Pressure
1.3.1 Temperature
The FDU90 can operate in a wide process temperature range of - 40 °C... 80 °C (- 40 °F... 176 °F). This makes it suitable for use in both cold storage applications and in processes where there is significant heat. In a food and beverage factory, it can be used to measure the level of products in cold storage tanks as well as in hot processing vessels. The sensor's ability to withstand such a wide temperature range is due to its robust construction and the use of materials that can maintain their integrity under different thermal conditions.
1.3.2 Pressure
The process pressure range for the FDU90 is 0.7 bar... 4 bar abs (10 psi... 58 psi). It can handle both low - pressure and moderately high - pressure environments. In a water treatment plant, it can be used in pipelines and tanks with different pressure levels, from the low - pressure influent lines to the higher - pressure effluent lines. The sensor is designed to be pressure - resistant, ensuring its proper functioning and longevity in these pressure conditions.

2.Features

2.1 Integrated Temperature Sensor for Time - of - Flight Correction
The integrated temperature sensor in the FDU90 is a key feature that contributes to its high accuracy. The speed of sound in a medium is highly dependent on temperature. As the temperature changes, the time it takes for the ultrasonic pulse to travel to the target and back will also change. The temperature sensor continuously monitors the temperature of the medium. The measured temperature is then used to adjust the time - of - flight calculation. For example, if the temperature increases, the speed of sound in the air (or other medium) will increase. The sensor's electronics will compensate for this by adjusting the time - of - flight value to ensure that the calculated distance remains accurate. This feature allows the FDU90 to provide consistent and reliable measurements even in environments where the temperature fluctuates significantly.
2.2 Hermetically Welded PVDF Sensor
The hermetically welded PVDF sensor offers several advantages. Firstly, the hermetic welding ensures a tight seal, preventing any ingress of moisture, dust, or other contaminants into the sensor. This is crucial for maintaining the sensor's performance and reliability, especially in harsh industrial environments. Secondly, PVDF is a material with excellent chemical resistance. It can withstand exposure to a wide range of chemicals, including acids, alkalis, and solvents. In industries such as chemical processing, petrochemicals, and pharmaceuticals, where corrosive substances are commonly handled, the PVDF sensor can operate for long periods without being damaged by chemical attack.
2.3 Separate Installation from the Transmitter
The FDU90 can be installed up to 300 m away from the transmitter. This separate installation feature is beneficial in several ways. It allows for greater flexibility in system design and installation. In large industrial plants, where the sensor may need to be placed in a difficult - to - reach location (such as the top of a tall silo or in a remote part of a wastewater treatment lagoon), the transmitter can be installed in a more accessible location, such as a control room or a central instrumentation cabinet. This makes it easier for maintenance and calibration purposes.
